Offset to Minimize the Impact of High Speed Connectors´ Crosstalk

With the development of electronic technology, the data transmission speed of PCB board has reached to 5 Gb/s, and this inevitably encounters signal integrity problems. For solving the problems, the current circuit is theoretical analyzed and a method is proposed to use offset to reduce the crosstalk between connectors´ differential pairs. By using simulation software, connector models are established and the differential pairs are analyzed. Both of theoretical and simulated methods had proven those results that adequate offsets could effectively reduce differential pairs´ crosstalk.
